Meet the JBO Thread Ring Gauge (NoGo) for Metric Fine threads. This right-hand NoGo gauge is designed to verify external M13 x 0.5 threads quickly and reliably, helping quality teams, engineers, and machinists confirm parts meet the specification. Crafted from hardened steel, its precise dimensions deliver consistent results across inspections in demanding environments.

• Exact M13 x 0.5 NoGo for metric fine threads: Provides a precise pass/fail on the maximum allowable diameter of external threads, enabling rapid, reliable checks and preventing non-conforming parts from moving forward.
• Hardened steel construction for long life: Withstands daily handling and repeated use while maintaining measurement accuracy through thousands of inspections in busy workshops.
• User-friendly ring design for fast inspections: Right-hand orientation with clear visual cues makes it easy to align and read, reducing setup time and operator errors on busy QA lines.

Using the JBO Thread Ring Gauge (NoGo) streamlines your quality control workflow. It helps you confirm thread compliance at a glance, speeds up inspections on high-volume runs, and reduces the risk of misfit parts in assembly. The durable construction means consistent results across shifts, while the straightforward design supports confident decisions and fewer rework iterations. Ideal for manufacturing, maintenance, and engineering teams handling metric fine threads, this gauge keeps your threaded components within specification and your processes running smoothly.
